1, I think the word writer is broader, and it includes poets. Writing can be used as poetry, lyrics, prose, travel notes and novels. You should mean the difference between a poet and a novelist. Personally, I think it is the same. Novelists also like to write poems, and poets can also write novels. There are many examples, such as Guo Moruo.
2. Poets' thinking is more active than ordinary people's, and ordinary people's thinking is relatively fixed. Poets are usually unconstrained and unconstrained, and ordinary people can't understand them, so they are called crazy.
The most prominent feature of poetry is lyricism. Poetry is emotional, the style of writing is generally short, but the essence is concentrated. For example, China's ancient lyric poems are short in length and extremely rigorous in composition, but they have a wide range of meanings, and the word can refer to thousands of miles. Modern poetry writing has flexible format, unlimited words and flexible content, which is convenient for expressing the author's strong feelings.
4. The prose of China's ancient poems is rigorous, which is limited by rhythm, diction, antithesis and levelness. Some people tease and dance in chains. However, the dance of China's ancient poets transcended the times. China's ancient poems are rich in content, either biographical, expressive, satirical or critical of history. The writing is exquisite and the artistic conception is beautiful.
On the other hand, excellent foreign poems are mostly narrative poems. More famous are Homer's ancient poems and Dante's Divine Comedy, which are detailed in narrative, combined with god and man, and magnificent in imagination. Limited to the study of ancient literature, I have only a little knowledge of foreign poetry, so I will take a glimpse of it for the time being.
